Mystery Of Greenland 'Object'
Solved By Data4Science

With all the mysterious images found on the web today,
it was time to take a closer look at one of these oddities. The mysterious
object is located in the country of Greenland, which even today is melting
at an incredible rate. We will look at this mysterious Greenland Object
someone has found on Google Earth, which also has at least one spooky-music
youtube video [1] describing it. Polar North is indicated in all images.
The youtube video shows what can happen when image data falls into
the hands of someone without an understanding of satellite imaging problems,
and who may not look for rational explanations.

Fig. 2 - Image of Greenland (like most all Google Earth
images) is constructed of a mosaic of images taken from satellites. These
images are taken in overlapping bands as these satellites orbit the Earth.
Lighting conditions vary with each exposure causing edges of individual
images to mis-match. Resulting mis-matched image borders create
faint diagonal, horizontal and vertical lines. Red circles added here indicate
some of the individual mosaic borders for various individual image areas.

Fig. 3 - Closeup of the mysterious object in question.
Here were can see that this object is simply a glimpse (in color)
of the landscape below. A false color yellow band is visible along
the top edge of the orange area, and can occur during image overlap. This image
segment may have been imaged by a different satellite on a cloudless
day, or imaged on a different day or perhaps even a different year.
Various light and dark areas of the area in question also tend to
be similar to those of the normal white image area shown just above it.

Fig. 4 - Closer view of the mysterious black object in
Fig. 1. What we see here is a total absence of any image in this area.
Perhaps data was missing from the original image mosaic.

There are many reasons for the black rectangle in Fig.
4 including operator error during image alignment, satellite data
dropouts, computer file processing errors, censoring, etc... Data for any
satellite image travels a VERY long journey from the time the image
data reaches Earth to Google Earth's image database. However, it's
highly unlikely the black rectangle itself is an actual object. Though
various articles and videos on the web focus more on the larger color rectangular
object (see Fig. 1.) the absence of any image area here is actually more
intriguing. If similar black rectangles do not appear on other Google Earth
images and in this image of Greendland, then perhaps something was actually found
here we are not supposed to see.
